Which of the following is the preferred method for splicing wires?
screw-on connectors |
|
wrap in small gauge wire |
|
soldering |
|
wire crimps |
Splicing is permanently joining two wires together. Splicing can be done with screw-on connectors or wire crimps but the preferred method for splicing is soldering. Soldering takes the most effort but results in a connection that is electrically and mechanically identical to the original wire.
The sum of the voltage drops across each resistor in a __________ circuit will equal the total voltage applied to the circuit.
series |
|
closed |
|
series-parallel |
|
parallel |
A series circuit has only one path for current to flow. In a series circuit, current (I) is the same throughout the circuit and is equal to the total voltage (V) applied to the circuit divided by the total resistance (R) of the loads in the circuit. The sum of the voltage drops across each resistor in the circuit will equal the total voltage applied to the circuit.
A diode to an electronic circuit is like a _______________ to a city?
highway |
|
parking lot |
|
one-way street |
|
traffic light |
A diode allows current to pass easily in one direction and blocks current in the other direction.
In a series circuit, which of the following is the same across all branches of the circuit?
conductance |
|
resistance |
|
current |
|
voltage |

The ampere is a unit of measurement for:
energy |
|
power |
|
inductance |
|
current |
Current is the rate of flow of electrons per unit time and is measured in amperes (A). A coulomb (C) is the quantity of electricity conveyed in one second by a current of one ampere.
